______ is generally used to increase the apparent size of physical memory.Question 12Select one:a.Disksb.Hard-diskc.Virtual memoryd.Secondary memory

Breakdown of the Problem

1. Identify the context of the question, which relates to computer memory.
2. Determine the available options and what increases the apparent size of physical memory.

Relevant Concepts

• Physical Memory: The actual RAM installed in a computer.
• Virtual Memory: A memory management capability that provides an "idealized abstraction" of the storage resources.

Analysis and Detail

1. Disks: Generally refer to physical storage devices but do not inherently increase memory size.
2. Hard-disk: A type of storage that also does not directly affect physical memory size.
3. Virtual Memory: This technique uses disk space to extend the usable memory in a computer system. It allows systems to handle larger workloads than what physical RAM would normally allow.
4. Secondary Memory: Refers to storage devices like hard drives and SSDs but does not specifically relate to increasing memory size.

Verify and Summarize

• Virtual memory explicitly allows systems to utilize more memory than is physically available by using disk space as an extension of RAM. This ensures applications can run smoothly even when they exceed the physical memory limits.

Final Answer

c. Virtual memory is generally used to increase the apparent size of physical memory.
